12-Bit Differential Input Micro Power Sampling  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
BIPOLAR INPUT RANGE  
The ADS7817 is a 12-bit, 200kHz sampling Analog-to-  
Digital (A/D) converter that features a high impedance fully  
differential analog input. The reference voltage can be var-  
ied from 100mV to 2.5V, with a corresponding input-  
referred resolution between 49µV and 1.22mV.  
TRUE DIFFERENTIAL INPUT  
200kHz SAMPLING RATE  
MICRO POWER: 2.3mW at 200kHz  
POWER DOWN: 3µA Max  
The differential input, low power, automatic power down,  
and small size make the ADS7817 ideal for direct connec-  
tion to transducers in battery operated systems, remote data  
acquisition, or multi-channel applications. The ADS7817 is  
available in a plastic mini-DIP-8, an SO-8, or an MSOP-8  
package.
